Example: PPP (Modem) passive dialup through PSTN
Setup at NetDVR end
Step 1: RS232 setup
Setup baud rate, data bit, stop bit, parity and flow control. They must be the same as those of modem connected with PC.
Step 2: Video setup
In “Recording” menu, select the camera you want to transfer video through PSTN. If you set CIF resolution, we suggest you set frame rate as 1 FPS. If you set QCIF
resolution, the frame rate can be selected under 4FPS. You can adjust bit rate, resolution and frame rate according to real conditions.
Step 3: Save setup
In “Recording” menu, press “Confirm” button to save parameters.

ATE0 ---- Not display the input characters
ATQ1 ---- Commit instruction and not display
